Plaster Crack Repair Versus Gyprock Repair


Drywall is a key component in any house, but it can be difficult to fix when something goes wrong. The solution often lies within removing just those parts which have been damaged.

In comparison, plaster walls are made up of two layers: the outer plaster and inner wooden or metal lath. If you have an older home with this type of finish, it’s best to preserve what exists and simply patch up the plasterboard rather than tearing out all existing materials.

Prepare The Surface For Gyprock Repair


When opening up the crack, use your putty knife to widen it and give more surface for plastering. Sand around any gaps or rough spots on paintwork so that everything is evened out before applying joint tape over these areas as well.

Fixing Drywall


When you have cracks in your gyprock, this is the most simple kind of crack to repair. After you have prepared the crack, cover each site with some joint tape and begin applying joint compound in layers. Extend these layers a few centimetres beyond the top and bottom of the crack and continue applying the compound until the crack is covered. Leave to dry and sand so it is ready for painting.

If you are dealing with a hole or large crack, it is often better to use a fine saw to remove the damaged area and replace it with fresh gyprock.

How To Cut Gyprock


It’s always better to use a saw that has fine teeth for cutting plasterboard. This will give you a cleaner cut than saws with wider teeth. It is recommended that you get specialised plasterboard or gyprock cutting saw because cutting through this material can dull the teeth on a traditional wooden saw. You can get a plasterboard or drywall saw from your local tool store.

How To Repair Plasterboard


A joint compound is a great way to fill in small cracks or gaps that form when water or water vapour seeps through the plaster. However, if you find yourself with an area pulling away from your lath because it has broken apart completely then there are two more steps before proceeding – first use a conditioner spray on both surfaces and then apply adhesive after letting them dry overnight.

This advice should be considered general in nature and it always pays to have the experts inspect any cracks you have in your home or business to ensure that there are no severe underlying causes.
